IMPROVEMENT IN TOBACCOfCASING MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame I, EDWARD HOLBROOK, Jr., of the city ofLou isville, county ofJefferson and State of Kentucky, have invented a certain new and usefulImprovement in Tobacco-casing Machines, of which the following is aspecification.

This invention consists in providing a small troughshaped case, securedto a suitable frameA or plat-forni, on one end of which case rests thestands or housing of a pair of small rolls, made somewhat similar to aclothes-wringer, the .outer surface of which is covered with a thickcoating of India rubber; the upper journal-boxes of the rolls are madeto slide in the stand, in order to adjust the rolls, which is done by aset-screw in the top.

The rolls are provided. with an apron or table, both on the receivingand discharge side, but the one on the receiving side is provided withangos at the sides, in order to keep the tobacco in place, and is alsoused as a table on which to lay the leaf-tobacco preparatory to beingsprinkled with the 'desired liquid preparation, which is supplied from a,small trough immediately above the entrance to the rolls.

The lower edge of this trough is made nearly sharp,

4with a long slot-hole in the under edge through which the liquid passesdown into anothertrough-shaped boni, attached to an adjustable slide, onthe under side of the iirst trough.

The under side of this last-named trough is perforated with holes, inorder to distribute the liquid more evenly over the surface, and toregulate the quantity required on the leaves before entering the rolls,theliquid for the purpose being supplied from thev large trough below,by means ol" elevator-cups att-ached t0 an endless chain, operated bypower applied to suitable pulleys above and below.

The one at the lowcrend is made to work in bearings made similar to aelevis, with a screw on one end, which passes through the end of thetrough,

-with a thumb-nut on the out-side, in order to take up the slack of thechain.

This chain and the rolls are driven by power applied by means of aseries of suitable pulleys and spur-gearing, a portion of which isattaehedto a small wooden iame erected on the platlbrni at the side ofthe large box, while. the others aro attached to the rolls on the box.

The object of my invention is to provide an economical and expeditiousmeans of saturating leaf tobacco with any desired liquid preparation,preparatory to Aa further process Vin its manufacture;

and also to distribute the liquid more evenly over. the

whole surface, in order that it may be pressed sufficiently dry for useas it passes through the rolls.

The manner of operatingl this invention is to pre-A pare the desiredliquid, and put it in the large trough below, the bottom of whichdescends to the elevators, by which the liquid is carried up anddeposited in a small trough over the rolls, the leaf tobacco beingplaced on the apron or table, ready to receive the liquid as it fallsgradually on the leaves as they pass through the rolls.

The top of the liquid-trough is made to answer as a table, on which toprepare the tobacco.

Having thus fully described my invention, a more complete understandingof which may be had by reference to the drawing* Figure l is avperspective view of the back part of the machine, showing the gearingby which it is driven.

Figure 2 is a view ofthe front of the machine, with apart of thecovering left oif, showing the interior ot' the liquid-box andelevators.

S S are coverings of the machine.

Ris the covering of the liquid-box, which is also used as a table onwhich to prepare the leaf tobacco.

L and N are the pulleys of the elevator-chain.

I) I? is t-he chain.

M M M are the elevator-cups, by means of which the liquid is raised fromthe box B, and deposited in the trough K.

Q is a thumb-nut, by which the slack of the clevator-ehain is taken up.

O is the clevis-bearing at the lower end, and is a guide for the chain,secured to the side of the boxframe.

Z is the discharge-table ot' the rolls.

Y Y Y are the cog-gearing of the rolls.
